i use ajax to create a session and to redirect the page when the user clicks on a button like this .. im using this in the facebook api(using the api to create a session with the user.id)
FB.login(function(response) {
if (response.session) {
FB.api('/me', function(user) {
if (user!=null) {
var request = new XMLHttpRequest();
if(document.getElementById("ans2").value==""){
document.getElementById("belowbutton2").innerHTML ="Don't leave it blank!!";
}
else{
var request2 = new XMLHttpRequest();
request.onreadystatechange=function(){
if(request.readyState==4 && request.status==200){
document.getElementById("debugger").innerHTML = request.responseText;
window.location = "weekques/weekques.php";
}
}
var uid = user.id;
alert(uid);
var jqXHR = ($.ajax)({url:"sessions.php?uid="+uid,
async:false,
cache: false,
timeout: 30000,
error:function(){
window.location = "http://www.xyz.com";
},
success:function(){
request.open("GET", "weekques/answer.php?ans="+document.getElementById("ans2").value, true); //+"&qid="+qidjs
request.send();
}
});
}
}
});
}
});
but the problem is that the window is redirecting before the session is created ..
heres the
sessions.php file
<?php
session_start();
require_once("connection.php");
$user=mysql_query("SELECT * from `thebirbals`.`FBusers` where uid='$uid';");
$row_count=mysql_num_rows($result);
$_SESSION['uid']=$_GET["uid"];
$uid = $_SESSION['uid'] ;
if($row_count==1){
$_SESSION['name'] = $check["name"];
$_SESSION['profile_link'] = $check["profile_link"];
$_SESSION['dp'] = $check["dp"];
}
else{
require_once('facebook/src/facebook.php');
$facebook = new Facebook(array(
'appId' => '1550598824560526',
'secret' => '4cf28242b5abfa26be8fd3e2074e5724',
'cookie' => false
));
$fql = "SELECT first_name,profile_url,pic_small from user where uid=$uid";
$response = $facebook->api(array(
'method' => 'fql.query',
'query' =>$fql,
));
foreach($response as $val)
{
$_SESSION['name']=$val["first_name"];
$_SESSION['dp']=$val["pic_small"];
$_SESSION['profile_link']= $val["profile_url"];
$name = $val["first_name"];
$profile_link = $val["profile_url"];
$dp = $val["pic_small"];
echo "done";
}
$insert=mysql_query("INSERT INTO `thebirbals`.`FBusers` ( `uid`, `name`, `profile_link`, `dp`) VALUES ('$uid', '$name', '$profile_link', '$dp');");
}
?>
i want to redirect after the sessions.php is finished running this does not happen
ty in advance for any help .. :)
I took a stab. Not sure if this will fix your issue entirely, but take it as a starting point:
FB.login(function (response) {
if (response.session) {
FB.api('/me', function (user) {
if (user != null) {
if (document.getElementById("ans2").value == "") {
document.getElementById("belowbutton2").innerHTML = "Don't leave it blank!!";
}
else {
var uid = user.id;
alert(uid);
$.ajax({ url: "sessions.php?uid=" + uid,
async: false,
cache: false,
timeout: 30000,
error: function () {
window.location = "http://www.xyz.com";
},
success: function () {
$.get("weekques/answer.php", $.param({ "ans": document.getElementById("ans2").value }), function (data) {
alert("Answer received");
document.getElementById("debugger").innerHTML = data;
window.location = "weekques/weekques.php";
});
}
});
}
}
});
}
});

I need to re render my homepage.ejs with new data on the server side after an ajax request. I know you can (somehow) re render the elements in the ajax callback but I was wondering if I could just re render my homapage.ejs since I have if statements that look for vacations, and current_user variables to set the right partialview.ejs
my ajax method:
function user_login(email, password) {
var data = {};
data.email_login = email;
data.password_login = password;
var message_header = $("#message_header");
$.ajax({
url: "/sign_in",
method: 'POST',
data: data
}).done(function (res) {
if (!res.success) {
message_header.text("Incorrect email of password. Please try again.").css("color", "red");
$("#username_textfield").val("");
$("#password_textfield").val("");
}
if (res.success) {
console.log("user logged");
}
});
my server side (inside of a query callback)
get_all_vacations(function (error, vacations) {
if (error) {
console.log("error when getting vacations " + error);
response.json({ success: false });
} else {
request.session.vacations = vacations;
response.render('the_vacation.ejs', { vacations : vacations, current_user : new_current_user }, function() {
response.json({success : true});
console.log("in render method");
});
}
});
i tried this but it does not work.
response.render('the_vacation.ejs', { vacations: vacations, current_user: new_current_user });
I think the simplest way, based on how your code is written would be to use window.location.reload(); when the login is successful.
function user_login(email, password) {
var data = {};
data.email_login = email;
data.password_login = password;
var message_header = $("#message_header");
$.ajax({
url: "/sign_in",
method: 'POST',
data: data
}).done(function (res) {
if (!res.success) {
message_header.text("Incorrect email of password. Please try again.").css("color", "red");
$("#username_textfield").val("");
$("#password_textfield").val("");
}
if (res.success) {
console.log("user logged");
window.location.reload(); // <--- Cause the browser to reload the EJS
}
});
I'm working on a cordova project and i'm using facebook login as one of the user authentication. The login works correctly but the issue is i have to press a button of an id getinfo before the values from facebook appear. But what i want to do is when the login is right the values should be appended automatically to the divs.
$(document).ready(function () {
$("#login").on('click', function (event) {
// Defaults to sessionStorage for storing the Facebook token
openFB.init({ appId: '000000000000000' });
// Uncomment the line below to store the Facebook token in localStorage instead of sessionStorage
// openFB.init({appId: 'YOUR_FB_APP_ID', tokenStore: window.localStorage});
openFB.login(
function (data) {
if (data.status === 'connected') {
$id = $("#id").append(data.id)
$name = $("#name").append(data.name)
$gender = $("#gender").append(data.gender)
$email = $("#email").append(data.email)
} else {
alert('Facebook login failed: ' + data.error);
}
});
});
});
how do i make my script work without using this below function
$(document).ready(function () {
$("#getinfo").on('click', function (event) {
openFB.api({
path: '/me',
success: function (data) {
console.log(JSON.stringify(data));
$id = $("#id").append(data.id)
$name = $("#name").append(data.name)
$gender = $("#gender").append(data.gender)
$email = $("#email").append(data.email)
document.getElementById("userPic").src = 'http://graph.facebook.com/' + data.id + '/picture?type=small';
},
error: errorHandler
});
});
});
Try this login function:
openFB.login(
function (data) {
if (data.status === 'connected') {
openFB.api({
path: '/me',
success: function (data) {
console.log(JSON.stringify(data));
$id = $("#id").append(data.id)
$name = $("#name").append(data.name)
$gender = $("#gender").append(data.gender)
$email = $("#email").append(data.email)
document.getElementById("userPic").src = 'http://graph.facebook.com/' + data.id + '/picture?type=small';
},
error: errorHandler
});
} else {
alert('Facebook login failed: ' + data.error);
}
});
});
Edit : I am using Adapter based authentication with worklight and angularJs. on click of login button i'm calling submitLogin procedure and pass the username and password in parameter as mention below. my query is after invocation of adapter how i'll return the authRequired value and WL.Server.invokeHttp(input) response simultaneously to the client side. i also mention challenge handler for authentication in login services code

I am trying to decrypt your question. It's not clear at all.
However there is already one thing that jumps out.
In your adapter you finished with:
return {authRequired: false, WL.Server.invokeHttp(input);};
You saying authRequired false even before checking if the credentials are valid?
You are supposed to parse the content of the results of WL.Server.invokeHttp(input) inside the adapter, decide if the credentials are valid.
If they are valid use setActiveUser before returning authRequired false.
Don't return the content of WL.Server.invokeHttp(input) to the client. This is meant for the adapter to parse.
See this tutorial: https://developer.ibm.com/mobilefirstplatform/documentation/getting-started-7-1/foundation/authentication-security/adapter-based-authentication/
I am using laravel 4 and I am trying to display login validation by using ajax. I have the following javascript validation:
jQuery('#form-signin').submit(function()
{
var url = $(this).attr("action");
jQuery.ajax({
url: url,
type: "post",
data: jQuery('#form-signin').serialize(),
datatype: "json",
beforeSend: function()
{
jQuery('#ajax-loading').show();
jQuery(".validation-error-inline").hide();
}
})
.done(function(data)
{
$('#validation-login').empty()
if (data.validation_failed === 1)
{
var arr = data.errors;
alert(arr);
}
else {
window.location = data.redirect_to;
}
})
.fail(function(jqXHR, ajaxOptions, thrownError)
{
alert('No response from server');
});
return false;
});
and in my userController:
public function doLogin() {
Input::flash();
$data = [
"errors" => null
];
if (Auth::attempt(array('email' => Input::get('email'), 'password' => Input::get('password')))) {
return Response::json(["redirect_to" => "/"]);
} else {
if (Request::ajax()) {
$response_values = array(
'validation_failed' => 1,
'errors' => 'Invalid username or password',
);
return Response::json($response_values);
}else
{
echo 'error';
}
}
}
The problem is that it always displays "error" message, which means that jaax request isn't performed. What is wrong?
In your doLogin() function try
return Response::json(array(
'validation_failed' => 1,
'errors' => 'Unknow error'
))
instead of
echo "error"
I am using facebook javascript sdk on my web application. I am using graph api to login my application. When I logged out from my application, my application is logged out and my facebook account is also logout.
How to logout only my application not my facebook account ?
Please help me if someone has found solution for this.
Code:
<script type="text/javascript">
var button;

Their is function defined in FB object use this to destroy FB session ,
usage( via PHP)
$facebook->destroySession();
Or
FB API provides a logoutURL which will log the user out of their current Facebook account.
you can use it like this ,
$facebook = new Facebook($config);
$params = array('next' => 'www.yousite.com/test.php' );
$logoutURL = $facebook->getLogoutUrl($params);
***note
advisable to add below codes also (not in case if you dont want your user to log out of your site)
//remove PHPSESSID from browser
if ( isset( $_COOKIE[session_name()] ) )
setcookie( session_name(), '', time()-7000000, '/' );
//clear session from globals
$_SESSION = array();
With JS using a custom event
ref : (FB.logout() called without an access token. javascript sdk)
function fbLogoutUser() {
FB.getLoginStatus(function(response) {
if (response && response.status === 'connected') {
FB.logout(function(response) {
document.location.reload();
});
}
});
}
